Scratch 2.0 (future)

Release as estimated is mid to late summer 2013. A public beta is starting on January 28th.

Variants:

Scratch Day alpha: Alpha version of the program and website made available as a preview from May 17 to May 21 for Scratch Day 2012. Features a new layout similar to the pre-alpha but with many graphical and several functional changes. Attendees of Scratch Day @ MIT were able to log in to the site and test cloud variables.

"Ye olde pre-alpha": Pre-alpha released by the Scratch Team at Scratch Day @ MIT 2011. Visually similar to Scratch 1.x versions with the layout of the Experimental Viewer and a few new features like cloning. Includes the Stamp Transparent () block which is unavailable elsewhere.

Release Candidate: Released on June 5, 2009, this version could be downloaded by people willing to test it out. It had a smaller palette of colours and was more buggy than the release version.

"Scratch Day Beta": Given out at the MIT Scratch Day celebration on May 16, 2009. One particular thing about this version is that it had a feature called Mesh, which allowed online connectivity.

Scratch 1.4.0.x: The versions of Scratch 1.4 for Ubuntu and other Debian-based Linux distributions, as well as Fedora and RPM-based distributions. These versions did not add any new features besides support for Linux. They range from 1.4.0.1 to 1.4.0.6, and the differences between each are mainly bugfixes.

Scratch 1.0

New features:
There were no public previous versions of Scratch to compare this to, so nothing was new. Alternately, one could say that everything was new.

Released on January 8, 2007,[1] this was the first version of Scratch available to the public.

Scratch 0.2

This version was developed in spring 2004. The known information about it is mostly from builds around March. Many of these features changed quite a bit and are not present in all versions, as Scratch was very actively being developed and things were being added and removed all the time. These are features known to be in at least some version.

Scratch 0.1

Scratch 0.1

Development on this version began in January 2003 and went up until its testing by Harvard and MIT students in October 2003. This preliminary testing led to the creation of the Stage in Scratch 0.2.[5]

New features:
This was the first prototype version of Scratch, so there were no new features
